体质特征就是DNA的外在反映,体质测量成本低、可以较大范围研究,缺点是辛苦、繁琐。但这是全世界都公认的人类学科学研究方法。

You are talking about the differences between the DNAs of Hakkas and Cantonese.
As we know,substituted pyrimidines are an important structural unit of DNA.Would
you like to tell us why all the three pyrimidines have at least two different isomers
and why the isomeration does not affect the normal function of the DNA? My questions are easy to those who have been taught the ABCs of biochemistry , but
I wonder whether you, who has his ideas supported by the researches in that field,
know what you are actually talking about when referring to them.
